OIL-BURNER ATTACHMENT FOR STOVES.

Specification of Letters Patent.

Application filed October 17, 1911.

Patented Feb. 20, 1912. Serial No. 655,145.

To all whom it may concern:

Be it known that I, ISAAC L. MITCHELL, a citizen of the United States,and a resident of Cedar Rapids, in the county of Linn and State of Iowa,have invented an Improvement in Oil-Burner Attachments for Stoves, ofwhich the following is a specification.

My invention comprises an oil vaporizer and burner and a supporttherefor which is so constructed that it may be placed in the fire-boxofa stove or other heater and supported detachably therein.

The details of construction, arrangement, and operation of theattachment are as hereinafter described, and illustrated in theaccompanying drawings, in which Figure l is a plan view of a portion ofa cook-stove with my improved oil-burner attachment arranged andsupported therein. Figs. 2 and 3 are cross sections of the attachment,the same being taken at right angles to each other. Fig. 4 is in themain a sectional View of the T-shaped head of the oil-supply pipe whichconstitutes the burner proper. Figs. 5 and 6 are perspective views ofthe two detachable portions of the oilburner support constituting theattachment proper.

In Figs. 1 and 2, the numeral 1 indicate an oil-supply pipe which isconnected with a spiral coil 2 and terminates in a T-shaped head 3 whosependent, perforated portions are located above the coil.

The coil and T head 3 constitute an oil vaporizer which is arranged in asupport A, B, so constructed that it may be placed and used in thefire-box of a cooking-stove or other form of heater. The details ofconstruction of such support are as follows. It is formed of ahorizontal to-p piece or portion A, and a pendent piece or portion B,which is right angular in shape, the said parts being cast separatelyand detachably connected by screw bolts 4, the same passing through thetop edge of the pendent part B and through a pendent flange (I of thepart A.

As shown in Figs. 1 and 5, the plate A has substantially an H-form intop view, the central portion 5 being narrow and the end portions 6broadened or extended laterally. The central portion 5 projects abovethe other part of the device and is open at the ends, as shown in Fig.3. This portion thereof thus constitutes a sort of hood beneath whichthe T head 3 is located, and

the open ends permit free access of air laterally to the burner tosupport combustion, which is a matter of great importance in allVaporizers of this type. In other words, the hood effectively protectsthe burner without hindering the desired accessibility of air thereto.

The broadened end portions 6 constitute flanges which, in the case ofthe cook-stove, as shown in Fig. l, overlie, or lap upon, the edges ofthe stove openings. The middle side portions of the part A are formed onthe arcs of circles which are coincident with, and form part of, astove-hole adapted to receive kettles, pans, or other forms of cookers.

The coil 2 of the vaporizer rests upon the horizontal orbase portion ofthe part B and directly over an asbestos pad 7 which, as shown in Fig.2, is held detachably in place by means of hook-shaped flanges 8. Thebase or part B is oblong and rectangular in shape and provided aroundits edge with a raised rib or flange 9, which serves to strengthen thepart B and serves also as means for preventing overflow of any oil thatmay drip on the base. The part B is provided with braces 10 oftriangular form, which further serve to strengthen the same.

My improved attachment being placed in a cook-stove in the manner shownin Fig. 1,

and oil turned on, the same will drip from the burner tips, and, beingignited, the heat is soon sufficient to vaporize the oil in the coil,thus producing a high degree of heat which extends laterally to thecooking utensils that may be placed in the stove holes.

lNhile the flanges 6 of the part A adapt the attachment for use incooking-stoves and for support therein, it is apparent that the broadflat base of the part B adapts the attachment for support upon a grate,or the bottom of a stove or other heater.

What I claim is 1. The improved oil-burner attachment for stoves,comprising a horizontal top plate A having a central raised hood open atits ends, side flanges adapted to rest upon the stove top, a pendentportion B having a right-angular form, one side of said pendent portionbeing secured to said top plate and the other side of said pendentportion forming a base, and an oil-vaporizing coil supported on the baseof portion B and having a T head Which projects into the aforeraisedhook-shaped flanges formed on said 10 said hood, substantially asdescribed. base, an asbestos Wick held in said flanges,

2. An improved oil burner attachment and a vaporizing coil supported onthe comprising 3 hfprizontal top plate having flanges above the Wick, asdescribed. horizontal si e anges adapted to rest upon a stove top and arightangular pendent por- ISAAC MITCHELL t-ion, one side of said pendentportion being Witnesses: secured to said top plate and the other sideALFRED L.
